Application August 27, 1951s, s m n r ans wz'oni s. (01. see-Q36 9 H v This invention relates to a carton assembling machine, and more particularly to such ama.- chine adapted for manual assembly of cartons. A primary object of this invention is the provision of an improved machine for the hand assembly of cartons soarranged and constructed as radially about a vertical shaft in such manner that the entire device is rotatable, whereby a plurality of cartons may be sequentially clamped on the device to permit the thorough drying of each carton before removal thereof.

An additional object of the invention is the provision of such a device wherein the clamping means are characterized by mechanism to insure even pressure throughout the entire base area of the carton during the gluing and drying operation.

A still further object of the invention is the provision of such a device which will be sturdy and durable in construction, reliable and eflicient in operation, and relatively simple and inexpensive to manufacture and assemble.

Other objects will in part be obvious and in part be pointed out as the description of the invention proceeds and shown in the accompanying drawings, wherein there is disclosed apreferred embod ment of this inventive concept.

In the drawings:

Figure 1 is a side elevational view of oneform of device embodying features of this invention,

Figure 2 is a top plan view of the structure shown in Figure 1,

Figure 3 is a fragmentary detail view disclosing one of the clamping devices comprising a feature of the invention, a different position of adjustment being indicated by dotted lines, and

Figure 4 is a fragmentary perspective view of a carton showing the method of assembling the same prior to positioning the carton on the device.

Similar reference characters refer to similar parts throughout the several views of thedrawings.

Having reference now to the drawings, there is generally indicated at Illa base comprised of a plurality of horizontal radial members I! terminating in supporting feet 12, and secured, at

their inner. ends as -by mea ns of a bolt l3,,t o a 'circular plate M. .The plate I4 is provided with a socket l5 from which. extends a vertical shaft IE, on which is mounted a rotatable plate 11. The upper extremity of the shaft I6 is provided with a collar l8 which may take the form .of a hearing, if desired, on'which ismounted asecond circular plate .1 9, the assembly being held in place as by a cap nut-20.

Extending radially-from plate H are a plurality of supporting members 2!, each including a-hori- "zontal portion 22'and a vertical portion-23. The

upper extremities of uprights 23' carryre'ctarigularplates 24, angularly disposed reinforcing members 25 serving to vmaintainthe plates in alignment. Additional angle plates 26 are also provided at the junctures of members 22 and" 23.

Extending vertically upward from intermediate points of members 22 are uprights 21, the upper extremities of which are secured to horizontal members 28 extending radially from plate I!) and having their inner ends secured thereto. Upper and'lower triangular reinforcing members 29 and 30, respectively, are provided at the juncturesof members 2! and Hand 21 and l2.

As best shown in Figure 2, each of the members 28terminate-s in a'transversely extending rodor bar 3|,nto the extremities of which arepivotally "secured as by pivots 32, additional horizontal members33, connectedloy a transverse plate 34. Asbest shown inFigure 3, each of the members 33 is provided with a pair of aligned apertures through {which extend the shanks of bolt memhas 35, the lower extremities of which are secured to press'plates 36. Bars 3! connect the upper extremities of aligned bolts 35 Coil springs -38 extend between aligned lugs 39 on bars -31 and corresponding lugs 40 extend upwardly from members 33. Thus it will be seen that, the

springs .38 cause a substantially equal pressure to be exerted on both extremities as well as .the intermediate section ,of each of the press plates 35, in a manner and fora-purpose to be described hereinafter.

iasihyia piyotrpin 42, an arm'43. AboltM carried r by the 43 extends through an arcua'teslot 45int purpose to be describedmore fully hereinafter. Secured to the upper extremity of the arm xten-sion plate 4| and provides for 1 adjustment of the arm in a manner and for a'- 3 43, as by a pivot 46, is a lever 41 having a bend 48 therein and terminating in a handle 49 normally extending in horizontal relation. Pivotally secured to the lever 41 at the bend 48, as by means of a pivot 50, is a link 5|, the opposite end of which is secured, as by a pivot 52, to a lug 53 extending upwardly from the center of transverse member 34. A detent 55, spring pressed as by means of a spring 56, is slidably secured to the underside of the horizontal portion of lever 41, in brackets 51, and engages a connecting rod 58, the opposite end of which is secured to one extremity of a T-shaped latch releasing handle 59, pivotally secured as by means of a pivot 60 to a point adjacent the handle 49. The spring 55 is anchored at one end to the detent shank, as by the pin 55'. The

opposite end of the spring is disposed on the seat 58' formed by one surface of one of the brackets Each of the members 33 is provided with an extending portion 6| which extends rearwardly of the pivot 32, and has mounted thereon a counterweight 62 adapted to be suitably moved to balance the assembly, and held in position as by a setg5 eluding parallel members having apertures therescrew 63.

. From the foregoing, the operation of the device should now be readily understandable. When it is desired to assemble a carton 65 (see Figure 4) one of the clamping members is moved by compress ng handle member 59 against handle-member 49, thus releasing latch 55 from keeper 54 which is secured to the upper horizontal edge of the link 5 I, to the dotted line position as indicated in Figure 3. The inner end flaps 88 of the carton carton thus folded is placed on one of the p'edestals 24, the sides '85 depending downwardly about the upright 23. The clamping assembly is then moved to the fullline position as disclosed in Figure 3, and latched, whereupon the press plates 36 distribute an even pressure over the flaps of the carton in folded position to secure the same until the adhesive or glue has thoroughly dried. While one box is drying, it will be readily apparent that the entire assembly may be rotated about the vertical upright IB until another pedestal 24 is positioned adjacent the operator, whereupon the entire operation is repeated. While in the illustrative assembly herein shown, six separate pedestals are provided, this quantity being deemed sufficient to permit thorough drying of each carton before the same is'again rotated to position in front of the operator for removal from its pedestal, it will be readily understood that the number of pedestals and associated clamping devices may be varied in accordance with the requirements of the particular use to which the machine is to be put.

In order to make it possible to handle cartons of different sizes on one machine, it is merely necessary to change the size of the rectangular plates 24.

From the foregoing, it will now be seen that there is provided herein an improved handoperated carton assembly device, particularly adapted for the use of small manufacturing plants wherein a comparatively small number of cartons,

as, for example, a few hundred, are required daily, and wherein the expense incident to the installation of relative expensive, fully mechanical carton-folding equipment would be unwarranted.

It will also be seen that there is herein provided a device accomplishing all of the objects of this invention, and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.

I claim:

1. In a device of the character described, a vertical support, a plurality of vertical pedestals radially positioned for rotation about said support, a clamping device secured to each pedestal. said clamping device including a horizontal member having an arm extending vertically therefrom, a lever pivoted to said arm, an extending frame pivoted to said member, said frame inin, bolts passed through said apertures, press plates secured to said bolts, transverse plates connected to the upper extremities of said bolts in each parallel member, springs connecting said transverse plates and an adjacent parallel member, whereby the springs through the transverse plates will move the press plates toward the container engaging position, and a link connecting said lever and said frame, said frame being adapted through said press plates to exert pressure on a carton carried by its associated pedestal.
